What Soil Mix Works Best for a Desert Stickleaf?

Well-draining sandy soil with some organic matter. Good drainage is essential for Desert Stickleaf to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Desert Stickleaf?

Feed Desert Stickleaf every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Where Should You Plant a Desert Stickleaf?

Choose a spot with full sun to partial shade and well-draining sandy soil with some organic matter. Avoid low spots where water collects after rain.

Desert Stickleaf is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

How Far Apart Should You Plant a Desert Stickleaf?

Desert Stickleaf can spread to about 2 ft (0.5 m) and reach about 2 ft (1 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Desert Stickleaf?

Prune Desert Stickleaf while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

How Do You Care for a Desert Stickleaf in Winter?

Desert Stickleaf is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

How Do You Propagate a Desert Stickleaf?

Desert Stickleaf can be propagated through seeds. Similar propagation techniques also apply to showy stickleaf plant care, which shares the same genus.
